Abstract

fetched live from OpenAlex

Nanoparticles have many applications in biomedical imaging, clinical diagnostics and therapeutics. Strategies that can reproducibly prepare colloidal nanoparticles of a wide range of geometries with a tight size distribution have been achieved and unique size and shape dependent optical, magnetic, electrical, and biological properties have been discovered. In spite of what has been achieved so far, a complete understanding of the interactions of cells with nanoparticles at the molecular level is lacking. This has led to the inability to rationally design nanoparticles for biomedical applications or has led to the inability to establish a definitive conclusion on the toxicity of nanomaterials. This presentation will focus on recent findings of the size and shape dependent interactions of nanoparticles with receptors on the cell surface. Specifically, data pertaining to the effect of antibody‐coated gold and silver nanoparticle size on regulating membrane receptor internalization and their subsequent signaling will be discussed. The findings presented here may assist in the design of nanoscale delivery and therapeutic systems and provide insights into nanotoxicity.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
